T0 ctZZ whom it may concern.-

Be it known that 1, JAMES SAMUEL FOLEY, manufacturer, of the city ofToronto, in the county of York, in the Province of Ontario, Canada, haveinvented a certain new and Improved Electrical Appliance for Operatingthe Signaling-Bell of a Locomotive, of which the following is aspecification.

The object of the invention is to design a simple electrical device bywhich the signaling-bell in the locomotive may be operated from any carin the train, and which will automatically operate the said bell shouldany car become accidentally detached from the train 5 and it consists inthe peculiar construction, arrangement, and combinations of parts,hereinafter more particularly described, and then definitely pointed outin the claims.

In the accompanying drawings, Figure 1 is a view which illustrates theapplication of my invention to railway-cars. Fig. 2 is a detail of thedevice for forming the electrical circuit in the car. Fig. 3 is a detailof the buifer by which the electrical connection is formed between thecars.

For the purpose of this description I will assume that theelectro-magnetic bellA is located in the locomotive at any convenientpoint in the cab. I prefer to locate the said bell at the point wherethe common signaling-bell is now usually placed, and I find it mostconvenient to locate the battery B under the seat of the driver. Thewire 0 is carried from its binding-post D, which is connected to onepole of the magnet in any 0011- venient manner toward the buffer E,which is held in contact with a correspondingly made and lettered bufferlocated on the next car, and to which the wire 0 in its car isconnected.

A wire F is arranged and connected in the same manner as the wire 0, butit of course leads from the opposite pole of the magnet. These two wiresare connected, respectively, to the two binding-posts G and H, as moreclearly shown in Fig. 2. In this figure it will be noticed that a leverI is pivoted on the binding-post G, to which the bell cord or wire J isconnected. A spring-finger K is riveted or otherwise suitably connectedto this lever I, and a springL is arranged to hold the said lever, asindicated in Fig. 2, away'from the binding-post H.

In order to close the circuit and thereby ring the bell A, it is ofcourse necessary that 5 5' the wire O and F should be electrically c011-nected. This connection is made in the car when the spring-fingerK isbrought into 0011- tact with the binding-post H, which may be readilyand instantly effected by drawing upon the bell-cord J.

I prefer to employ a spring-finger K instead of making the 001111 ectiondirectly with the lever I, as it will act as a scraper when it comes incontact with the surface of the bind ing-post H, and thus insure anelectrical connection by the removal of any nonconduct ing substancewhich may have accumulated on the said post. lVith the view of stillfurther insuring this removal I serrate the edge 7 of the finger K, asindicated in Fig. 2. When the bell-cord J is released, the springLforces the lever I, with its finger K, away from the binding-post H, andin this manner the circuit is broken, and the signal-bell in the 10-coinotive will cease ringing. Every car in the train will of course bewired, as described, and each will be provided with an independentbell-cord J.

Having described the manner in which the circuit is closed inside thecar, I shall proceed to explain briefly the mechanism by which theelectrical connection is made between the cars, and how, in the event ofthe car becoming accidentally disconnected, the circuit is automaticallyclosed and the signal announcing the accident conveyed to the signal-bell of the locomotive. The butter IE, it will be observed, isadjustably fitted onto the spindle M, which is screwed or otherwisefixed onto the end of the car, as indicated.

A spring N is fitted into the buffer E, against the end of the spindleM, as indicated in Fig.

8. When two cars are brought together, the opposite buffers on the twocars are held to- 9 5 geth er by the action of their respective springsN, which permit sufficient motion of the cars in rounding curves andhold the buifers together by an elastic pressure.

0 is a metal rod suitably secured to the bottom of the car and having abent end 1) arranged to project up opposite to each of the lugs P,formed on the buffer E.

When the cars are coupled together, the buffers E are compressed so asto move the lugs P away from their respective ends b, formed on the rod0; but should the car be accidentally uncoupled the spring N in eachbuffer E will push its buffer so as to bring the lug P on the bufferagainst the end 1) cpposite to it, thus forming an electrical connectionbetween the two bufiers and the wires 0 and F, thereby completing thecircuit and causing the bellA to ring. As the buffers on the end of thelast car of a train will not be pressed, and consequently the ends I) ofthe metal rod 0 must necessarily be in contact with the lugs P on thebuffers at this end of the car, I divide the rod 0 and complete it by apivoted pieceQ, which in the last car I leave open, so as to break thecircuit and prevent the constant ringing of the bell, which wouldotherwise occur.

What- I claim as my inventioii is 1. In an electric signaling apparatus,the wires 0 and F, connected to an electromagnetic bell, the buffersE,n0r1nally electrically connected to the wires to form an electricalconnection between the cars, as described, in combination with thebinding-posts G and H, a circuit-making mechanism, as the lever I, and abell-cord J, connected to said lever, substantially as described.

2. In an electric signaling apparatus, the wires 0 and F, connected toan electro-magnetic bell, the buffers E, normally electrically connectedto the wires to form an electrical connection between the cars, asdescribed, in combination with binding-posts G and H, the lever I,pivoted to post G, the scraping-finger K, attached to lever I andscraping the post H, and a bell-cord J, connected to said lever, allsubstantially as shown and described.

3. In an electric signaling apparatus, the combination of the two wires0 and F, two compressible buffers E, connected, respectively, to anelectro-magnetic alarm by said wires 0 and F, and having contacts, asthe lugs-P, with a conductor, as the rod 0, for making connectionbetween the two wires, substantially as described.

4. In an electric signaling apparatus, the combination of two wires 0and F, two compressible buffers E, connected, respectively, to anelectro-magnetic alarm by said wires 0 and F, and having contacts, asthe lugs P, with a conductor, as the rod 0, for making connectionbetween the two wires, and a circuit-breaker Q in said conductor,substantially as described.
